f yApplication iilei'Augu'st 4, IQQZ.

Be it known thatI,"JonN Rrronrn RICH-, MOND, a subject otyHis. Majesty the fKingzrot Great Britain, residingatGla-sgow, Scotland,-A have invented a certain newandusefulIrn` provenient in Steam Surface Condensers, of which the followingis a specification.

My invention relates to steam surface condensers of that class infwhich the circulating water passes through-thetubes and the steam is on the outside of-the latter.

The object of my invention is to provide a simple and effective construction of appara! tus in which the airrand Water of condensation can be withdrawn separately, the latter particularly being taken od before it is un duly cooled and its heat wasted.

A construction oi' apparatus according to myinvention is illustrated in the accompanying drawings, inwhich- Figure l is a longitudinal section. Fig. 2 is a plan. Fig. 8 is a section on line A A, Fig. l, looking in direction of the arrow. Fig. 4 is a section in line B B, Fig. Llooking in the direction of the arrow. Fig. 5 is a section on line C C,'Fig. 1, looking in the direction of the arrow.

The condenser consists of a casing c, having tube-plates b b at either end, between which are supported the tubes c for the circulating water. The inc-losing ends d d of this casing o. tbus'form two chambers e e, the latter being divided longitudinally by a diaphragm g,l Fig. 4L. r"With the chambers so formed on either side of diaphragm g are con` nected aninleth'and outlet 2, respectively,v for theucirculatingwater.

The portion of the condenser between the tube-plates b b formsa chamber, .which is divided into two portions by a transversedi'- visionplate or 'diaphragm j, having an aperture la, Fig. 5, on the opposite side to the steam-inlet,hereinafter referred to,such plate j being so situated thatthe larger or primary portion of the condenser on the right is twothirds (or more) and the smaller or secondary portion on the left is one-third (orless) of the whole. In the larger or 'primary portion may be arranged, as shown, a steady-.plate l, Fig. 3, for the tubes, such plate having apertures fm, n o or beingotherwise more or less open for the circulation of steam in the larger por- Serial No.y 118,354, (No model.)

i tion. Tol enable this tobe edectual, some of the tubes are omitted, as shown, Where these gaps occur, onefof. them, o, corresponding with the gap k in the division-plate j. The

plate Z, however, is, as stated, merelyasteadychamber is provided with a iioat-tank s of the usual kind.

In operation the cooling-water enters inlet 71, and circulates through one half of the tubes, then through chamber e, and returns by the other half to outlet 'L'. The steam enters through inlet p and mainly condenses in the larger or primary portion of the condenser, though a portion will pass into the smaller or secondary portion, thewater of condensation in the latter chamber passing by Siphon-pipe r into thelarger, whereit joins the water of congilensation of the latter and passes to the Heat-tank and away.

The air, it will be seen, can be withdrawn by a pump or in other ways from the outlet q in the smaller chamber at a comparatively low temperature, while the bulk of the water of condensation from the larger chamber remains atia comparatively high temperature and can be withdrawnin that condition.

The construction enables a considerable eft'lciency in working to be secured.

1. In asteam surface condenserand in combination, a chamber having aprimary portion and a secondary portion, the former beingy of considerably greater size than the latter, and having an outlet for the water of condensation while the latter vhas an outlet for the air, a diaphragm forming a division between such chambers, and having an opening therein, means connecting the two chambers for drawing the water of condensation from the secondary to the primary and means for circulating cooling-water through such chambers, substantiaily as described.

2. In a steam surface condenser, and in combination a chamber a,circu1ating-water tubes c therein means for supporting saine and chambers e, f, having inlet and outlet for the circulating Water a partition-plate g dividing the chamber j' between the inlet and outlet, a diaphragm j dividing the chamber a. into a primary and secondary portion of Which the primary is the larger said primary portion having an opening forming a steam-inlet and an opening forming an outlet for the Water of condensation and said secondary portion
